Adjusting and fixing device on ski bindings



Nov. 8, 1938. w. HONEGGER ADJUSTING AND FIXING DEVICE ON SKI BINDINGS Filed March 4, 1937 Patented Nov. 8, 1938 UNITED STATES PATENT OFFICE ADJUSTING AND FIXING DEVICE ON SKI BINDINGS land Application March 4, 1937, Serial No. 129,061 In Switzerland March 10, 1936 1 Claim.

The present invention relates to an adjusting and fixing device on ski-bindings. This device enables a fine adjustment of the toe-jaws and an adaptation thereof to the shoe which can be effected positively and with little expense of time.

The accompanying drawing illustrates, by way of example, an embodiment of the invention.

Fig. 1 is a plan view of the invention, a part of the covering plate being removed.

Fig. 2 shows a cross-section along the line AB of Fig. 1.

Referring to the drawing in detail, I represents a base-plate as ordinarily used on skis,

5 two pairs of spring acting adjusting and fixing arms 2 being rockably mounted thereon by means of screws 3 which are screwed into the base-plate, said arms 2 being bent at their fixing end. Each of said arms 2 is provided with a downwardly 20 projecting pin 4. Each toe-jaw 5 has two groups of grooves or notches extending along an arc of a circle and being formed with recesses 6 arranged in pairs, into two opposite ones the pins 4 of the rocked arms 2 may be forced in 25 order to fix the jaws 5 in their adjusted position. The adjusting and fixing of the jaws 5 by means of the arms 2 and their pins 4 can be positively effected with great exactness and with little expense of time. When the arms 2 30 are adjusted the pins 4 of the arms 2 are allowed to yieldingly engage with the respective recesses 6 whereupon the jaws rest irremovably in the adjusted position.

The adjusting arms 2 may be rigid and in this 35 case they must be lifted for the length of the pins 4 when the jaws shall be displaced after the screws 3 have been loosened. With spring like adjusting arms a loosening of the screws 3 is not necessary.

For adjusting, the jaw portions are forced towards the shoe while the jaws are opened and the fixing screws firmly tightened. Afterwards 5 the adjusting and fixing arms are rocked and the pins forced into the corresponding recesses 6 whereupon the screws of the adjusting and fixing arms are tightened.

The toe-jaws 5 are positively held in the di- 10 rection across the ski when the adjusting pins 4 are forced into the recesses 6 and the screws 3 are tightened. For displacing of the jaws 5 the adjusting and fixing arms 2 are rocked into the longitudinal axis of the ski after the screws 3 are loosened. The arms 2 may be laminated.

Both ends of each toe-jaw being adjustable in the present ski-binding, a very fine and precise adjustment of the toe-jaws and complete security against all displacements are obtained.

What I claim is:

An adjusting and fixing device on ski-bindings, comprising a front pair and a rear pair of adjusting and fixing arms, a pin on each of said arms, a pair of adjustable toe-jaws of angular section, a group of grooves in each toe-jaw opposite each of said arms, said grooves extending along arcs of a circle eccentric to the rocking axis of the corresponding adjusting arm and diiferent distances from this axis, recesses formed in opposite pairs on the edges of said grooves and adapted to receive said pins, a base plate having a screw between the said adjustable toejaws, serving as a rocking axis for the said arms and as a means to firmly hold the said pin between one or another pair of said recesses.
